Suicidal behavior occurs across all ages, backgrounds, and cultures, and it is rarely driven by a single cause. Understanding the function of suicidal behavior is essential for effective assessment and treatment. In this blog, we explore the behavioral functions of suicidal actions and how Dialectical Behavior Therapy (DBT) helps individuals reduce risk by addressing the emotional pain driving these behaviors.
The Functions of Suicidal Behavior
Suicidal behavior does not occur randomly. From a DBT and behavioral perspective, it often serves specific functions for the individual. Identifying these functions is essential for effective, compassionate treatment. While the functions vary from person to person, several common patterns are frequently seen in clinical work.
Expression of Emotional Pain
For many individuals, suicidal behavior reflects overwhelming emotional suffering. When distress feels intolerable and unmanageable, suicidal thoughts or behaviors may emerge as a way to externalize internal pain and signal the seriousness of that suffering to others.
Maladaptive Coping
Suicidal behavior can function as a short-term coping strategy when emotions such as sadness, fear, anger, or shame feel unbearable. Although harmful, the behavior may temporarily reduce emotional intensity, reinforcing it as a learned response to distress.
Sense of Control
In situations where life feels chaotic or powerless, suicidal behavior may create a temporary sense of control or agency. This function is especially common among individuals with trauma histories, where personal autonomy has been repeatedly violated.
Communication of Distress
Some individuals use suicidal behavior as a way to communicate needs they feel unable to express verbally. While not always a conscious intention, the behavior may function to elicit care, attention, or intervention from others when emotional needs feel unseen or invalidated.
Escape or Avoidance
Suicidal thoughts may function as an escape from perceived unbearable circumstances, such as chronic stress, interpersonal conflict, or significant life transitions. The idea of escape can momentarily reduce emotional pain, even when it increases long-term risk.
Identity and Belonging
Particularly among adolescents and young adults, suicidal behavior may become linked to identity or peer belonging. When self-harm or suicidal thoughts are normalized within social groups, the behavior can be reinforced through connection and shared experience.
How DBT Can Help
Because suicidal behavior serves different functions for different individuals, effective treatment must address the underlying emotional and behavioral drivers. Dialectical Behavior Therapy (DBT) was specifically developed to treat chronic emotion dysregulation, suicidal behavior, and self-harm. Created by Dr. Marsha Linehan, DBT integrates cognitive-behavioral strategies with mindfulness-based practices to promote safety, skill development, and long-term change.
Validation of Emotions
DBT begins with validation. Individuals learn that their emotions are real, understandable responses to their experiences, even when those emotions feel overwhelming. Validation reduces shame and helps people feel seen and understood, creating the foundation for meaningful change without reinforcing harmful behaviors.
Skills Development
DBT teaches practical, evidence-based skills that help individuals manage emotional distress without resorting to self-harm or suicidal behavior. These include:
•Mindfulness: Learning to observe thoughts, emotions, and urges without judgment. Mindfulness reduces impulsivity and increases awareness through tools such as DBT diary cards.
•Distress Tolerance: Building the ability to endure emotional pain safely using self-soothing, grounding, and crisis-survival strategies. Therapists may provide coaching during high-risk moments to prevent impulsive decisions.
•Emotion Regulation: Identifying emotions, understanding triggers, and learning strategies to reduce emotional vulnerability.
•Interpersonal Effectiveness: Strengthening communication and boundary-setting skills to improve relationships and reduce conflict-driven distress.
Behavioral Analysis
A core component of DBT is behavioral analysis. Therapists work collaboratively by examining a diary card that the client completes daily and which is an important tool to use along with the chain analysis. This is used to examine the events, thoughts, emotions, and urges that lead to suicidal thoughts or actions. Understanding the function of the behavior allows for the development of safer, more effective coping strategies.
Building a Support System
DBT emphasizes the importance of connection. Clients learn how and when to reach out to trusted supports, including family members, peers, or therapists. A strong support system helps reduce isolation and increases safety during emotionally vulnerable moments.
Crisis Management and Risk Assessment
DBT prepares individuals for crises through personalized safety planning. At Suffolk DBT, clinicians use evidence-based tools such as CAMS and LRAMP to assess suicide risk and guide treatment. Clients may access skills coaching between sessions to receive support during moments of acute distress or urges to self-harm.
Long-Term Change
DBT is not only about crisis stabilization—it is designed to support lasting change. By consistently practicing skills and building emotional resilience, individuals learn to navigate life’s challenges with greater stability, self-trust, and hope, reducing the risk of future suicidal behavior.
Conclusion
Understanding the reasons behind suicidal thoughts and behaviors matters because every person’s experience is deeply personal. These struggles are often shaped by emotional pain, overwhelming feelings, and a longing for relief or connection. When those experiences are met with understanding rather than judgment, real healing becomes possible.
Dialectical Behavior Therapy offers a compassionate and practical path forward. Through DBT, individuals learn skills to manage intense emotions, feel more grounded, and respond to life’s challenges in safer, healthier ways. With the right support, people can move beyond surviving each day and begin building a life that feels meaningful and worth living.
If you or someone you love is struggling with suicidal thoughts or behaviors, you do not have to face this alone.
